I can see how a Wren would be pretty easy to use with a HH. Probably the only bag that is user friendly in a HH. Plus, being encapsulated in down just has to be sweet.
This looks like a nice mod.
Custom Feathered Friends Rock Wren.
Modified full length zipper to function as top quilt. Modified grosgrain loops to function as Hennessey underquilt. 2oz overfill, pertex quantum inside and out
I will have to agree with Rasputen. I have a couple HH's, and a a couple ENO's. I use a BA Lost Ranger with a thermarest mil issue pad. I have used it down into the low 30's, and could easily hit the high 20's with comfort. Happy Hanging.
I trust everyone, it is the devil in side them i dont trust.
I use a Campmor 20* down bag. $109.99 and very good quality. On a 24* night, snowing/freezing rain/6-8mph wind with my JRB underquilt and the campmor bag only, I was TOASTY. I start with the bag unzipped and you stick it in the hammock first, then push it to the side when you get in. Then put your feet in the foot pouch and pull the bag over you. Use it like a quilt with a footsack or just tuck it in around you on the sides.
Works really well for me.
well as I have a HHED think i can comment on this one.
I have a few bags some central / some right side zips. so the following
british army sleeping system - great bag central zip, bit heavy.
softie elite 3 - another great bag, right zip, packs down to nothing.
I tend to use the softie now as its easier to get into my bergan, lightweight and good warmth rating.
When cold, I use a Big Agnes Mystic long left-zip with a Ridgerest Deluxe of matching size (78 x 20). Open the bag all the way, sit on the sleeved pad in the middle of the bag, rotate about 90°, lay down, pull top of bag over you and zip up as required. You can then toss and turn inside the spacious bag (and I do) without worrying about the pad slipping around under you. IMO this setup is perfect for a Hennessey's bottom-mount system.
When warm, I use as little as possible, a cheap fleece bag or even a Coolmax sheet. It gets *very* hot and humid down here in the summer. I'm getting older and starting to wuss out on going out in the summer, sticking to spring/fall/winter camping.
